Filed: 1990-08-06
Abstract: PURPOSE:To hold a required quantity of solder in a hole so as to obviate the need for solder replenishment which is necessary for flat cables to be connected to electronic appliances and the like, by providing holes passing through in the thickness direction and embedding solder in the holes. CONSTITUTION:A plurality of flat conductors 1 are disposed in parallel in one plane, portions except its part are sandwiched to be integrated with insulating tapes 5.

Abstract: PURPOSE:To prevent the adhesion of scales to a water level detecting strip and to avoid a bad influence due to the rising of waves in the surface of water in a water tank by a method wherein the water level detecting strip is fixed to the inside of a protection cylinder. CONSTITUTION:In case where water is stored in the water tank 4 of a humidifier 1 up to a proper level, when infrared ray lamps 15 are lighted up by turning a main switch ON, the stored water 5 applied with infrared rays from the lamps 15 begins to vaporize from the surface thereof.

Title: Overload detecting method
Inventor: UCHIUMI HIROAKI
IPC: G01R19/165
Filed: 1986-09-05
Abstract: PURPOSE:To confirm the state of an overload from the level of a flowing current by comparing the maximum value of a crest value obtained from sampled values at two optional points having a 90 deg. phase difference with respect to the three-phase current of a power source with a load current for overload detection, and judging from the detected value whether the overload is temporarly or not. CONSTITUTION:The output of a pulse generating means which generates pulses of frequency 12 times as high as that of the three-phase power source to be detected is used as sampling pulses to obtain sampled values of the three-phase signal at two optional points having a 90 deg. phase difference. The maximum value I<2>max among crest values of respective phases which are obtained from the sampled values is compared with the value by multiplying the rated current I0 of the load by several percent to detect the overload from the comparison result. Then when a timer means which begins to operate on the detection of the overload discriminates cold characteristics, hot characteristics are processed on condition that the comparison result is smaller than a set constant; and the overload is judged when the result is equal to or smaller than the constant. Further, when the process of hot characteristics is entered, the overload is judged if the comparison result is larger than the constant.

Filed: 1992-07-13
Abstract: PURPOSE:To enhance heat transfer efficiency and simplify structure as well. CONSTITUTION:During cold storage time, a coolant 60 is housed in an ice heat storage tank 50. The brine 70 cooled in a brine cooling tank 50 with a first valve 13 closed is supplied to the ice heat storage tank 10. When the first valve 13 and a second valve 31 are opened while a pump is still being operated, the coolant 60 will move from the ice heat storage tank 10 to a heat exchanger 30 by way of a transportation line 20 by differential specific weight. When the pump 40 is halted and the second valve 31 is closed, the brine 70 falls by self-weight from the end of the second valve 31. When an air to be cooled is introduced from an air suction pipe, and forced the air to flow between the clearance of the coolant 60 and discharged from a vent pipe 33, heat exchange takes place on the surface of the coolant 60, thereby carrying out cooling operation.
